I don't want to take away your hope or your trans identity. All I am saying is that you cannot just decide to call yourself a woman, because being a woman is a lot more than how you feel about yourself and necessarily involves quite a bit of biology.
I am very much in favor of safe spaces, sports categories, etc for trans identified people if they feel they need it. But women also need their own safe spaces, sports categories, etc which are exclusive to us. Invading those spaces is not fair to us. Invading lesbian safe spaces and then kicking us out of them because we are only interested in relationships with biological women is not fair to us. Go make "transbian" communities if you want, we would not complain, we are not oppressing you. But stop appropriating us and kicking us out of our own house.
